背景技术Background technique
在日常生活中，不同的环境需要的光线色温不尽相同。例如，家用白炽灯为2500～3000K，车载灯光需要色温在3000～6000K，摄影灯光色温不同也会对照片的实际效果产生影响。具体的，例如，目前的车载灯光都是分别设置雾灯、近光灯、远光灯等多个不同色温的灯光系统，行车途中需要根据不同的行车环境下启用不同色温的灯光。常用的车灯色温在3000K～6000K之间，在这个色温范围内，色温越高，亮度越高，穿透力越差。所以在雨雾天气，通常选用雾灯，该灯的色温范围为3000K～4000K，该段色温的光具有很好的穿透性，有助于行驶安全；而近灯，色温范围通常在4000K～5000K，尤其是色温为4300K的光，兼顾穿透性与亮度；而在一般的夜晚行车，通常选用远光灯，色温范围一般为5000K～6000K，该段色温的光，视野表现更好。In daily life, different environments require different light color temperatures. For example, household incandescent lamps are 2500-3000K, and car lights need a color temperature of 3000-6000K. Different color temperatures of photography lights will also affect the actual effect of photos. Specifically, for example, the current vehicle lighting is equipped with multiple lighting systems with different color temperatures, such as fog lights, low beams, and high beams. It is necessary to use lights with different color temperatures according to different driving environments during driving. The color temperature of commonly used car lights is between 3000K and 6000K. In this color temperature range, the higher the color temperature, the higher the brightness and the worse the penetration. Therefore, in rainy and foggy weather, fog lamps are usually used. The color temperature range of the lamp is 3000K-4000K. The light of this color temperature has good penetrability, which is helpful for driving safety; while the near lamp, the color temperature range is usually 4000K-5000K. , especially the light with a color temperature of 4300K, which takes into account both penetration and brightness; while driving at night, high beams are usually used, and the color temperature range is generally 5000K to 6000K. The light with this color temperature has better visual field performance.
由上可知，对于现有技术中的车灯装置，为分别设置雾灯、近光灯、远光灯等多个不同色温灯源的灯光系统，行车途中需要根据不同的行车环境下启用不同色温的灯源。即，现有技术中存在在需要多种不同色温的灯光装置时，需设置多种不同色温光源的问题，进而存在灯光系统复杂，成本较高的问题。It can be seen from the above that for the car light device in the prior art, it is a lighting system with multiple light sources with different color temperatures, such as fog lights, low beam lights, and high beam lights. Different color temperature lights need to be activated according to different driving environments during driving. light source. That is, in the prior art, when multiple lighting devices with different color temperatures are required, it is necessary to install multiple light sources with different color temperatures, and furthermore, the lighting system is complicated and the cost is high.

具体实施方式detailed description
下面结合说明书附图对本申请实施例的实现过程进行详细说明。需要注意的是，自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。The implementation process of the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are only for explaining the present application, and should not be construed as limiting the present application.
参见图1，本申请实施例提供一种灯光装置，包括：光源2以及设置在光源2出光侧的至少一个液晶结构1，液晶结构1包括阵列基板13、对向基板14以及设置于阵列基板13与对向基板14之间的液晶层15，液晶结构1用于根据预设条件将光源2的光转换为预设色温光。阵列基板13在背向液晶层15的一侧还可以设置第一偏光片(图中未示出)，对向基板14在背向液晶层15的一侧还可以设置有第二偏光片(图中未示出)。Referring to FIG. 1 , an embodiment of the present application provides a lighting device, including: a light source 2 and at least one liquid crystal structure 1 disposed on the light emitting side of the light source 2 , the liquid crystal structure 1 includes an array substrate 13 , an opposite substrate 14 and a liquid crystal structure disposed on the array substrate 13 . Between the liquid crystal layer 15 and the opposite substrate 14 , the liquid crystal structure 1 is used to convert the light from the light source 2 into light with a preset color temperature according to preset conditions. The array substrate 13 can also be provided with a first polarizer (not shown in the figure) on the side facing away from the liquid crystal layer 15, and the opposite substrate 14 can also be provided with a second polarizer (not shown in the figure) on the side facing away from the liquid crystal layer 15. not shown).
需要说明的是，图1中仅是以灯光装置设置有一个液晶结构进行的举例说明，本申请不以此为限制。在具体实施时，灯光装置的液晶结构可以为一个，也可以为多个。灯光装置包括一个液晶结构时，可以通过使液晶结构在不同区域具有不同的Δnd(Δn为液晶的双折射率，d为液晶层厚度)，使液晶结构将光源的光转换为不同色温的光；灯光装置包括多个液晶结构时，可以通过多个液晶结构调节光的传播路径，并搭配在光传播路径上设置的有色膜层，最终使光源的光转换为不同色温的光。It should be noted that, in FIG. 1 , the lighting device is only provided with a liquid crystal structure for illustration, and the present application is not limited thereto. In a specific implementation, there may be one or more liquid crystal structures of the lighting device. When the lighting device includes a liquid crystal structure, the liquid crystal structure can convert the light of the light source into light of different color temperatures by making the liquid crystal structure have different Δnd (Δn is the birefringence index of the liquid crystal, d is the thickness of the liquid crystal layer) in different regions; When the lighting device includes multiple liquid crystal structures, the propagation path of the light can be adjusted through the multiple liquid crystal structures, and the colored film layer arranged on the light propagation path can be matched to finally convert the light from the light source into light with different color temperatures.
对于通过使液晶结构在不同区域具有不同的Δnd，以将光源的光转换为不同色温的光，具体可以保持整个液晶结构的液晶层厚度d一致，通过使液晶结构在不同区域具有不同的双折射率Δn，进而以具有不同Δnd；或者，可以保持整个液晶结构的双折射率Δn一致，通过使液晶结构在不同区域具有不同的液晶层厚度d，进而以具有不同Δnd。其中，图2为软件模拟出的Δnd与色温的关系变化图，其中，横坐标表示Δnd，纵坐标表示色温，D1为色温为6459K的固定色温光源，D2为色温为5487K的固定色温光源，由图2可知，灯光装置出射的光的色温随着Δnd的改变而改变，进而在需要确定的色温光时，可以确定出对应的Δnd。以下通过具体的实施例，对通过使液晶结构在不同区域具有不同的Δnd以将光源的光转换为不同色温的光进行具体举例说明。For converting the light from the light source into light with different color temperatures by making the liquid crystal structure have different Δnd in different regions, specifically, the thickness d of the liquid crystal layer of the entire liquid crystal structure can be kept consistent, and by making the liquid crystal structure have different birefringence in different regions Ratio Δn, and thus have different Δnd; or, the birefringence Δn of the entire liquid crystal structure can be kept consistent, by making the liquid crystal structure have different liquid crystal layer thickness d in different regions, and then have different Δnd. Among them, Figure 2 is a diagram of the relationship between Δnd and color temperature simulated by the software, where the abscissa represents Δnd, and the ordinate represents the color temperature. D1 is a fixed color temperature light source with a color temperature of 6459K, and D2 is a fixed color temperature light source with a color temperature of 5487K. It can be seen from FIG. 2 that the color temperature of the light emitted by the lighting device changes with the change of Δnd, and then when light with a certain color temperature is required, the corresponding Δnd can be determined. The conversion of light from a light source into light with different color temperatures by making the liquid crystal structure have different Δnds in different regions will be specifically illustrated below through specific examples.
实施例一，参见图3，本申请实施例一提供一种灯光装置，包括：一个液晶结构1以及设置在该液晶结构1入光侧的光源2，光源2具体可以为背光模组，其中，液晶结构1包括阵列基板13、对向基板14以及设置于阵列基板13与对向基板14之间的液晶层15，对向基板14上还可以设置有黑矩阵18，阵列基板上还可以设置有公共电极19。液晶结构1包括多个去除了色阻膜层且呈阵列分布的像素单元16(图中仅示出了一个像素单元)，每一像素单元16包括三个子像素单元，分别为：第一子像素单元161、第二子像素单元162以及第三子像素单元163。其中，对向基板14在面向液晶层15的一侧设置有平坦层141，平坦层141在与子像素单元对应的区域设置与该子像素单元对应的预设膜层厚度。即，与第一子像素单元161对应的平坦层141的厚度为D1，与第二子像素单元162对应的平坦层141的厚度为D2，与第三子像素单元163对应的平坦层141的厚度为D3，液晶结构1根据预设条件，通过控制光源2的光透过确定的子像素单元，进而将光源2的光转换为与该子像素单元相对应的预设色温光。Embodiment 1, referring to FIG. 3 , Embodiment 1 of the present application provides a lighting device, including: a liquid crystal structure 1 and a light source 2 arranged on the light incident side of the liquid crystal structure 1. The light source 2 may specifically be a backlight module, wherein, The liquid crystal structure 1 includes an array substrate 13, an opposing substrate 14, and a liquid crystal layer 15 disposed between the array substrate 13 and the opposing substrate 14. A black matrix 18 may also be arranged on the opposing substrate 14, and a black matrix 18 may also be arranged on the array substrate. Common electrode 19. The liquid crystal structure 1 includes a plurality of pixel units 16 (only one pixel unit is shown in the figure) with the color-resist film layer removed and distributed in an array. Each pixel unit 16 includes three sub-pixel units, which are respectively: the first sub-pixel A unit 161 , a second sub-pixel unit 162 and a third sub-pixel unit 163 . Wherein, the opposite substrate 14 is provided with a flat layer 141 on the side facing the liquid crystal layer 15 , and the flat layer 141 is provided with a preset film thickness corresponding to the sub-pixel unit in a region corresponding to the sub-pixel unit. That is, the thickness of the flat layer 141 corresponding to the first sub-pixel unit 161 is D1, the thickness of the flat layer 141 corresponding to the second sub-pixel unit 162 is D2, and the thickness of the flat layer 141 corresponding to the third sub-pixel unit 163 is D1. D3, the liquid crystal structure 1 controls the light from the light source 2 to pass through a certain sub-pixel unit according to preset conditions, and then converts the light from the light source 2 into light with a preset color temperature corresponding to the sub-pixel unit.
即，对于本申请实施例一提供的灯光装置，该种灯光装置与现有的显示面板的结构较为相近。光源为现有显示面板的背光模组，液晶结构为经过改进后的液晶盒，即，本申请实施例一的液晶结构相比与现有技术的液晶盒，去除了液晶盒中的彩膜基板上的彩膜，并使平坦层在不同区域形成不同的厚度，进而使阵列基板和对向基板在不同区域形成不同厚度的间隙，再在二者之间注入液晶时，可以在不同区域形成不同厚度的液晶层，而光源的光在经过不同厚度的液晶层后会转换为不同的色温。即，例如，若该灯光装置为车灯装置，需设置色温依次降低的A、B、C三种色温的光，则需要在液晶结构的每一像素单元对应设置三个子像素单元。若选取的光源的色温为6459K的固定色温光源，液晶的双折射率Δn为定值，则，根据图2所示的Δnd与色温的对应关系，可以确定出具体每一种色温的光需要的Δnd值，进而可以确定出d的值，进一步可以确定出每一子像素单元具体需设置的平坦层的厚度。而在具体实施时，若当前为雨雾环境，为了车灯装置出射具有较好穿透性的C色温光，则可以通过对液晶结构的控制，使液晶结构的第三子像素单元对应的液晶进行偏转，使光源的光能够经过该第三子像素单元并进行出射，而使第一子像素单元和第三子像素单元的液晶不发生偏转，进而最终可以使液晶结构只在各个像素单元的第三子像素单元出射色温为C的光(假设第三子像素单元对应的平坦层的厚度可以出射C色温的光，而第一子像素单元对应出射A色温的光，第二子像素单元对应出射B色温的光)。That is, for the lighting device provided in Embodiment 1 of the present application, the structure of this lighting device is relatively similar to that of an existing display panel. The light source is the backlight module of the existing display panel, and the liquid crystal structure is an improved liquid crystal cell, that is, compared with the liquid crystal cell of the prior art, the liquid crystal structure of the first embodiment of the present application removes the color filter substrate in the liquid crystal cell The color film on the upper surface, and make the flat layer form different thicknesses in different regions, and then form gaps with different thicknesses in different regions between the array substrate and the opposite substrate, and then inject liquid crystals between the two to form different thicknesses in different regions. The thickness of the liquid crystal layer, and the light from the light source will be converted into different color temperatures after passing through the liquid crystal layer with different thicknesses. That is, for example, if the lighting device is a vehicle lighting device, and it is necessary to provide lights with three color temperatures of A, B, and C with decreasing color temperatures in sequence, three sub-pixel units need to be provided correspondingly in each pixel unit of the liquid crystal structure. If the color temperature of the selected light source is a fixed color temperature light source of 6459K, and the birefringence Δn of the liquid crystal is a constant value, then, according to the corresponding relationship between Δnd and the color temperature shown in Figure 2, the specific light requirements for each color temperature can be determined The value of Δnd can further determine the value of d, and further determine the thickness of the flat layer that needs to be set for each sub-pixel unit. In actual implementation, if the current environment is rainy and foggy, in order for the car light device to emit light with a C color temperature with good penetrability, the liquid crystal corresponding to the third sub-pixel unit of the liquid crystal structure can be controlled by controlling the liquid crystal structure. deflection, so that the light of the light source can pass through the third sub-pixel unit and exit, so that the liquid crystals of the first sub-pixel unit and the third sub-pixel unit are not deflected, and finally the liquid crystal structure can be only in the first sub-pixel unit of each pixel unit The three sub-pixel units emit light with a color temperature of C (assuming that the thickness of the flat layer corresponding to the third sub-pixel unit can emit light with a color temperature of C, while the first sub-pixel unit corresponds to emit light with a color temperature of A, and the second sub-pixel unit corresponds to emit light with a color temperature of C).

对于蓝相液晶，其与电场强度之间具有如下的关系：For the blue phase liquid crystal, it has the following relationship with the electric field strength:
其中，Es为饱和电场强度，E为施加不同电压下的电场强度；Δns为饱和电场强度下的双折射率，即，可以通过改变施加在蓝相液晶上的驱动电压不同，得到不同的Δnd，以达到改变出射光线色温的目的。Among them, Es is the saturation electric field strength, E is the electric field strength under different voltages;Δns is the birefringence index under the saturation electric field strength, that is, different driving voltages applied to the blue phase liquid crystal can be changed to obtain different Δnd , in order to achieve the purpose of changing the color temperature of the outgoing light.
即，对于本申请实施例二提供的灯光装置，该种灯光装置与现有的显示面板的结构较为相近。光源为现有显示面板的背光模组，液晶结构为经过改进后的液晶盒，即，本申请实施例二的液晶结构相比与现有技术的液晶盒，去除了液晶盒中的彩膜基板上的彩膜，所使用的为蓝相液晶，而蓝相液晶可以在不同的电压下形成不同的双折射率Δn，进而在液晶结构的不同子像素单元对应的区域施加不同的电压时，可以使该区域的液晶具有相对应的双折射率，而光源的光在经过不同双折射率的液晶层后会转换为不同的色温。即，例如，若该灯光装置为车灯装置，需设置色温依次降低的A、B、C三种色温的光，则需要在液晶结构的每一像素单元对应设置三个子像素单元。若选取的光源的色温为6459K的固定色温光源，在液晶结构的液晶层的厚度d为定值时，则，根据图2所示的Δnd与色温的对应关系，可以确定出具体每一种色温的光需要的Δn值，而根据蓝相液晶与电场强度的关系，可以进一步确定出需要施加的电压值。在具体实施时，若当前为雨雾环境，为了车灯装置出射具有较好穿透性的C色温光，则可以通过对液晶结构的控制，对第三子像素的单元施加相对应的电压，使第三子像素单元的液晶具有相应的双折射率，并使液晶结构的第三子像素单元对应的液晶进行偏转，使光源的光能够经过该第三子像素单元并进行出射，而使第一子像素单元和第三子像素单元的液晶不发生偏转，进而最终可以使液晶结构只在各个像素单元的第三子像素单元出射色温为C的光(假设第三子像素单元对应电压下的折射率可以出射C色温的光，而第一子像素单元对应电压下的折射率可以出射A色温的光，第二子像素单元对应电压下的折射率可以出射B色温的光)。That is, for the lighting device provided in Embodiment 2 of the present application, the structure of this lighting device is relatively similar to that of the existing display panel. The light source is the backlight module of the existing display panel, and the liquid crystal structure is an improved liquid crystal cell, that is, compared with the liquid crystal cell of the prior art, the liquid crystal structure of the second embodiment of the present application removes the color filter substrate in the liquid crystal cell The color film above uses blue-phase liquid crystal, and the blue-phase liquid crystal can form different birefringence Δn under different voltages, and then when different voltages are applied to the regions corresponding to different sub-pixel units of the liquid crystal structure, it can The liquid crystal in this area has a corresponding birefringence index, and the light from the light source will be converted into different color temperatures after passing through the liquid crystal layers with different birefringence indexes. That is, for example, if the lighting device is a vehicle lighting device, and it is necessary to provide lights with three color temperatures of A, B, and C with decreasing color temperatures in sequence, three sub-pixel units need to be provided correspondingly in each pixel unit of the liquid crystal structure. If the color temperature of the selected light source is a fixed color temperature light source of 6459K, when the thickness d of the liquid crystal layer of the liquid crystal structure is a constant value, then, according to the corresponding relationship between Δnd and color temperature shown in Figure 2, each specific color temperature can be determined The Δn value required by the light, and according to the relationship between the blue phase liquid crystal and the electric field strength, the voltage value that needs to be applied can be further determined. In actual implementation, if the current environment is rainy and foggy, in order for the car light device to emit light with a C color temperature with good penetrability, the corresponding voltage can be applied to the unit of the third sub-pixel by controlling the liquid crystal structure, so that The liquid crystal of the third sub-pixel unit has a corresponding birefringence, and deflects the liquid crystal corresponding to the third sub-pixel unit of the liquid crystal structure, so that the light of the light source can pass through the third sub-pixel unit and be emitted, so that the first The liquid crystals of the sub-pixel unit and the third sub-pixel unit are not deflected, and finally the liquid crystal structure can only emit light with a color temperature of C in the third sub-pixel unit of each pixel unit (assuming that the refraction of the third sub-pixel unit under the corresponding voltage The refractive index of the first sub-pixel unit can emit light of color temperature C, and the refractive index of the first sub-pixel unit can emit light of color temperature A, and the refractive index of the second sub-pixel unit can emit light of color temperature B).
由于不同的RGB三基色也可以改变白色光的色温，对于本申请实施例一和实施例二提供的液晶结构，也可以在对向基板上设置RGB三基色，RGB与Δnd控制配合可以达到更宽的色温控制范围。Since different RGB three primary colors can also change the color temperature of white light, for the liquid crystal structures provided in Embodiment 1 and Embodiment 2 of this application, RGB three primary colors can also be set on the opposite substrate, and the combination of RGB and Δnd control can achieve a wider range. color temperature control range.
